Sorry Frances but, until you told me, I must confess my ignorance of your authorship, and I cannot remember exactly where I stumbled across it.
All I can remember is noting that after the death of Esther Cashin her sibling, Elizabeth, also married William Caine, at a time when such marriages were expressly forbidden but, as they married in Toxteth, Liverpool, this may explain how it escaped the notice of Manx authorities.
It aroused my interest so I "Googled" the Internet to see what I could find on the subject and I freely acknowledge that what I turned up should have been credited to you.
Please accept my sincere apologies for the omission.
